JULES D. BSCAYART AND FERNAND CAILLETEAU, OF ATLANTA, GORGIA.

MEANS FOR OPERATING ELECTRC-LAMP SWITCH-BUTTONS.

Application led September 5, 1917.

To all whom 'it may concern:

i Be it known that JULES D. BISCAYART and FERRAND Cixinnn'rnan, citizens of the United States, residing at Atlanta, in the county 0f Fulton and State of Georgia, have invented certain new and usei'ul Improvements in Means for Operating Electric-Lamp Switch- Buttons; and they do hereby declare the following to be a full, clear, and exact description of the invention., such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and iigures of reference marked thereon, which forni a part of this specification.

This invention relates to new and useful improvements in attachments to snap switches and consists in the provision of a simple and efficient device of this nature, adapted to be held by resilient fingers upon a bulb socket and having a spring pressed slotted oscillating member for the reception oiLl the button of the switch and a single cord attachment for turning the member in one direction.

@ur invention consists of a simple and ei''- ficient device of `this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

Vile illustrate our invention in the accompanying drawings, which with the letters of reference thereon form a part of this application and in which:

Figure l is an edge view in elevation showing the application of the invention to a bulb socket.

Fig. 2 is a front elevation.

Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Fig. 4 is a View in elevation with the outer shell removed, and

Fig. 5 is a perspective detail view of the pawl pin.

Reference now being had to the details of the drawings by letter:

A designates a ring having two resilient fingers A projecting therefrom at points diametrically opposite and forming means for attachment to the bulb socket. Said ring has slots B formed therein at the base of said fingers and adapted to receive the lugs C of the housing D having a central Patented Apr. 30, i9i@.

serial No. 189,880.

opening D therein and which with the ring form inclosures for the operative parts of the device. has two shoulders F and H, the former of which has a bearing in the circular outlined opening of the ring, and said shoulder H a bearing in the circular outlined opening in said housing. Said shell has a series of circumferential perforations J formed therein and is provided with intersecting slots K for the reception of the button ol' a switch.

it circumiierentially grooved ring, designated by letter L, is joui-n aled about the perforated portion oft' said shell and has oppositely disposed lugs N struck up therefrom carrying the pivotal pin O upon which a pawl l? is pivotally mounted and the pawl has a hooked end passing through the slot R in said circumferentially grooved ring and which pawl is adapted to engage the perforations or' the shell when the ring carrying the pawl is moved in one direction, thus causing the shell to rotate with the ring. A lug T is struck up from the inner tace of the ring A and one end of a coiled spring is attached to said lug T and its other end is attached to a struck up lug R in the wall of the groove of the ring. The purpose of said spring is to normally return the pawl carrying ring to its normal. position after having been rotated by a cord or chain S which is fastened to the circumference of they ring, and which is guided in the groove of the ring and passe-s through a slot X in the housing.

ln operation, the spring lingers are caught over the socket of the bulb, the key to a switch passing through one of the intersecting slots. W hen the device is thus securely held upon the socket, by pulling upon the cord the grooved ring to which the same is attached may be given a partial rotary movement and the pawl carried by the ring engaging the perforated shell will cause the latter to rotate and return the switch button against the tension of the coiled spring. When the cord is released the spring will return the ring to its starting position, the pawl turning idly over the circumference of the shell.

What we claim to be new is:

l. A device for operating buttons of snap switches comprising a ring and means for attaching the same to a bulb socket, an oscillating cylindrical shell j ournaled in said ring and having a slot i'or the reception of a switch, a grooved ring journaled upon said A. cylindrical slotted shell E shell, a cord attached to and adapted to be guided in said groove, a paWl pivotally mounted upon the grooved ring and having its free end passing through a slot therein, the circumference of the shell being perforated to receive the pawl, a spring attached to one end of the grooved ring and its other end to the stationarg,7 ring.

2. A device for operating buttons of snap switches comprising .i ring and means for attaching the same to a bulb socket, an oscilo latin'g cylindrical shell liournaled in said ring and having a slot 'orthe'reception of a switch, a grooved ring journaled upon said shell, a cord attached to and adapted to be guided in said groove, a paWl pivotally mounted upon ther grooved ring and having its free end passing through a slot therein, the circumference of the shell being perforated to receive the paWl, said rings each having a struck up lug, and a spring attached to said lugs adapted to return the shell to its starting position.

3. A device for operating buttons of snap switches comprising a ring having resilient fingers for engagement with a bulb socket and provided With slots, a housing having lugs engaging said slots, a cylindrical shell having shouldered portions journaled in the openings of said ring and housing and having a series of circumferential perforations, a grooved ring journaled about said shell and having a slot therein and lugs struck up from the opposite edges, apawl pivoted upon said lugs `with its iree end passing through the slot in the ring and adapted t0 engage the perforations of the shell to said rings, a cord fastened to the grooved ring, and a housing about the grooved ring.

In testimony whereof we hereunto affix our signatures in presence ,of two Witnesses.
